Clinical management of Nutcracker's syndrome during pregnancy.

Background: The Nutcracker syndrome (mesoaortic compression of the left renal vein) is a rare condition which causes macroscopic hematuria and colic pain.

Methods: We have carried out a search in Medline database of the current trends in the management of this rare syndrome during pregnancy.

Results: We found four reports on diagnosis of the syndrome during pregnancy but there is no published articles concerning the management of pregnancy after diagnosis of a Nutcracker syndrome treated with a vascular stent. A case of Nutcracker's syndrome during pregnancy is reported as well as a review of the clinical findings and management of the syndrome.

Conclusion: The pregnancy of patients with Nutcracker syndrome, undergone vascular stent placement, should be considered high risk gestation and should be managed with low molecular weight heparin and serial renal vein flow Doppler studies.
